What kind of chiller is this?

How does it compress the refrigerent? It does not make the typical chiller sound I am used to hearing, much quieter.

How old is it, and how many tons? Should I be budgeting for replacement and if so, what is a good option?

It is unusual for me to see a chiller at a small, 8,000 sf building, which unfortunately, is a reheat system, very high utility bills, but I have not figured out any way to convert it to a better system.

Thanks everyone for being so helpful.

Not small chiller for that building. It can take care of fresh air.
As for re-heat strategy was the old school when electricity was dirt cheap. Today, it is illigal to engineer that. As for this building, It will requires better strategies and DDC logics to reduce the elctric bills. The owner would never understand the up-front cost and the saving in the long run.

A Carlyle semi-hermetic is more quiet than a 19XR centrifugal with no sound kit!

I don't think that you are going to find a 20-25 ton centrifugal chiller. :-) The compressor is enclosed in a cabinet and they are usually quiet enough. Good chillers for the most part as long as you have enough water and a load on them. The one in this post is probably showing its age.

True on the tonnage aspect. But if you put up a rack of Carlyle 06E's (as many higher tonnage recip chillers have) against a screaming 19XR in a loudness contest, I think the high pressure centrifugal would still win. The 06E's purr in comparision to that ear drum shattering squeal.

OTOH a large tonnage recip chiller (one or two large compressors) can crank out some sound.

My church has 2 condensing units behind the parish hall. One looks like the chiller pictured except DX, the other is a notch smaller, maybe a 15 ton. When they are on, between the Carlyles and the fans, you can hear them for a block. The big boy for the sanctuary is behind a stone wall 15' high. 1 Carlyle on isn't too bad and fortunately that usually does it. But both on, walking across the courtyard you sure hear them. But then I can remember hearing one centrifugal in the past. Don't recall if Trane or Carrier. Had a loud whine seems to me.
